This patch makes Cancel() call PostUpdate which clobbers certain state in style
so that animated style is correctly flushed when an animation is cancelled.
The main difficulty with this is that we *don't* want to call this when we're
cancelling an animation as a result of a style update or else we'll trigger
needless work. The pattern elsewhere has been to define a *FromStyle() method
for this case (e.g. CSSAnimation::PlayFromStyle, PauseFromStyle). This isn't
ideal because there's always the danger we will forget to call the appropriate
*FromStyle method. It is, however, consistent. Hopefully in bug 1151731 we'll
find a better way of expressing this.
This patch also updates the method names on PendingAnimationTracker but leaves
a number of local variables which will be fixed in a subsequent patch.
--HG--
rename : dom/animation/PendingPlayerTracker.cpp => dom/animation/PendingAnimationTracker.cpp
rename : dom/animation/PendingPlayerTracker.h => dom/animation/PendingAnimationTracker.h
This patch is a fairly minimal rename of the AnimationPlayer interface. It
leaves a bunch of local variables and helper classes still using the word
"player". These will be addressed in subsequent patches that don't require DOM
peer review.
--HG--
rename : dom/animation/AnimationPlayer.cpp => dom/animation/Animation.cpp
rename : dom/animation/AnimationPlayer.h => dom/animation/Animation.h
rename : dom/webidl/AnimationPlayer.webidl => dom/webidl/Animation.webidl
This patch also tightens up a one or two references to 'target effect' replacing
them with just 'effect'. This is because 'target effect' is longer and easily
confused with 'target element'. 'effect' should be sufficient. 'target element'
is a term from the Web Animations specification and in that context, simply
referring to the 'effect' would sound a little odd.
There are still some other references to "source" in AnimationPlayer such as
HasInPlayerSource and UpdateSourceContent. These are renamed in a subsequent
patch (that doesn't require DOM peer review).
We define KeyframeEffectReadonly in KeyframeEffect.cpp since Web Animations also
defines KeyframeEffect and when we come to implement that I expect we'll define
it in the same class, maybe even using the same object.
This patch also adds a few missing includes in places where
KeyframeEffectReadonly is used so that we're not just cargo-culting it in.
--HG--
rename : dom/animation/Animation.cpp => dom/animation/KeyframeEffect.cpp
rename : dom/animation/Animation.h => dom/animation/KeyframeEffect.h
rename : dom/animation/test/css-animations/test_animation-name.html => dom/animation/test/css-animations/test_effect-name.html
rename : dom/animation/test/css-animations/test_animation-target.html => dom/animation/test/css-animations/test_effect-target.html
rename : dom/animation/test/css-transitions/test_animation-name.html => dom/animation/test/css-transitions/test_effect-name.html
rename : dom/animation/test/css-transitions/test_animation-target.html => dom/animation/test/css-transitions/test_effect-target.html
rename : dom/webidl/Animation.webidl => dom/webidl/KeyframeEffect.webidl
Most of this is fairly obvious. However, the addition of 'override' to
ElementPropertyTransition::Name() is not strictly necessary. It was simply added
because while making these changes I accidentally dropped the 'virtual' keyword
from the method in the superclass and the compiler didn't complain. Adding this
will hopefully make it harder to create the same bug in the future.
--HG--
rename : dom/animation/test/css-animations/test_animation-effect-name.html => dom/animation/test/css-animations/test_animation-name.html
rename : dom/animation/test/css-transitions/test_animation-effect-name.html => dom/animation/test/css-transitions/test_animation-name.html
This is a bit awkward. We lazily set mName to the transition property and then
return it. The reasons for this approach are:
* We don't really want to eagerly fill in mName for all transitions since in
99% of cases we'll never use it and this will lead to wasted allocations.
* The signature of Name() returns a const nsString reference. This is because
Name() is used when building CSS Animations (to compare different copies of
the same animation when updating). For that case we don't really want to
generate unnecessary copies of nsString objects so we return a reference.
However, that means for transitions as well we need to return a reference so
we can't just generate a temporary string on-demand.
As a result we also have to const-cast ourselves so we can update the mName
member. We could make mName mutable but seeing as it's only set once, the
const_cast seems more appropriate.
The tests in dom/animation/tests/ use an old version of idlharness.js that
doesn't support inherited interfaces. As discussed in bug 1152619 we're not
looking at updating these old tests (under dom/imptests) at the moment which
means we won't be able to update the IDL tests in dom/animation/tests/ to
continue passing once we introduce DocumentTimeline as a subinterface of
AnimationTimeline.
As a result, this patch simply the removes the IDL tests for this interface from
dom/animation/tests. However, we have a test for this interface in
web-platform-tests where I've set up a pull request to apply the required
renaming so we should eventually get test coverage for this renaming.

In the long run, all the tests in dom/animation/tests should end up in
web-platform-tests. The main reason they aren't there yet is that most of them
test the mapping between the Web Animations API and CSS and there's currently no
spec defining that so there's no place to put them in the web-platform-tests
repository.
There are a few tests for animation timeline which could be landed in
web-platform-tests (and then removed from dom/animation/tests) but we need to
discuss with Google if this is the desired behavior or not first. For the time
being I have a branch setup for that and I'm leaving the tests in
dom/animation/tests so we continue to test what *we* think the behavior should
be in the meantime. That branch is here:
https://github.com/birtles/web-platform-tests/compare/rename-animation-timeline...birtles:add-hidden-iframe-tests
(I don't understand the motivation for the changes to how it was set,
but this just switches to having two variables for the two uses.)
This fixes the test failures in test_animations_omta.html with OMT
animations enabled.
